371091 ÷ 39 
We want to figure out the number of times 371091 can be divided by 39.

On to step 1:
3 divided by 39 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 39

Going ahead to step 2:
If we divide 37 by 39, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 39

On to step 3:
39 goes into 371 9 times with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 351 from 371 leaves us with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 39

Step 4:
200 divided by 39 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtracting 195 from 200 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 39

Advancing to step 5:
39 goes into 59 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 951.0
If we subtract 39 from 59, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 39

Step 6:
If we divide 201 by 39, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 9515.0
The remainder is 6 after subtracting 195 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 39, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 9515.1
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
39 can be fit into 210 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 9515.15
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
If we divide 150 by 39, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 9515.153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 9515.1538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 9515.15384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 9515.153846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
If we divide 60 by 39, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 9515.1538461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
If we divide 210 by 39, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9515.15384615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 9515.15384615, and the remainder is 1.5e-08.
